            Status: UNCONFIRMED

I am using the cubieboard (embeded arm linux) trying to develop a video play
using gstreamer and qt5. I ported gstreamer 1.4.5 to arm. It works well with
playbin and xvimagesink. But as I want to output the vedio using my qt window,
the movie played as well but no image was shown in the window, nor any errors
reported. But the similar project works well on the PC. 
As a result, I tried compiling the test project of overlay named
qtgv-videooverlay, still there's no vedio frames and no error. 
Can anyone tell me some possible cause of my problem? Thanks so much.
